Alexandros--

Alexander the Great (born 356 bce, Pella, Macedonia [northwest of Thessaloníki, Greece]—died June 13, 323 bce, Babylon [near Al-Ḥillah, Iraq]) was the king of Macedonia (336–323 bce), who overthrew the Achaemenid Empire, carried Macedonian arms to India, and laid the foundations for the Hellenistic world of territorial kingdoms. Already in his lifetime the subject of fabulous stories, he later became the hero of a full-scale legend bearing only the sketchiest resemblance to his historical career.

First invasion of Thrace--

Left in charge of Macedonia in 340 during Philip’s attack on Byzantium, Alexander defeated the Maedi, a Thracian people. Two years later he commanded the left wing at the Battle of Chaeronea, in which Philip defeated the allied Greek states, and displayed personal courage in breaking the Sacred Band of Thebes, an elite military corps composed of 150 pairs of lovers. A year later Philip divorced Olympias, and, after a quarrel at a feast held to celebrate his father’s new marriage, Alexander and his mother fled to Epirus, and Alexander later went to Illyria. Shortly afterward, father and son were reconciled and Alexander returned, but his position as heir was jeopardized.
